Definitions

  • Document DE 10 2012 016 737 A1 discloses a disc brake for a vehicle brake system that comprises a restoring spring engaging a brake pad assembly and biasing the brake pad assembly under elastic deformation into an initial position in which there is no braking effect.
  • This invention relates in general to vehicle disc brake assemblies and in particular to an improved structure for a brake clip for use in such a disc brake assembly.
  • a typical brake system for an automobile or light truck includes a disc brake assembly for each of the front wheels and either a drum brake assembly or a disc brake assembly for each of the rear wheels.
  • the brake assemblies are actuated by hydraulic or pneumatic pressure generated when an operator of the vehicle depresses a brake pedal.
  • the structures of these drum brake assemblies and disc brake assemblies, as well as the actuators therefore, are well known in the art.
  • a typical disc brake assembly includes a brake rotor which is secured to a wheel of the vehicle for rotation therewith.
  • the disc brake assembly further includes a caliper assembly that is slidably supported on pins secured to an anchor bracket.
  • the anchor bracket is secured to a non-rotatable component of the vehicle, such as the axle flange or steering knuckle, which is connected to the vehicle frame.
  • the caliper assembly includes a pair of brake pads which are disposed on opposite sides of the brake rotor.
  • the brake pads are connected to one or more hydraulically or pneumatically actuated pistons for movement between a non-braking position and a braking position, wherein the brake pads are moved into frictional engagement with the opposed braking surfaces of the brake rotor.
  • the piston urges the brake pads from the non-braking position to the braking position so as to frictionally engage the opposed braking surfaces of the brake rotor and thereby slow or stop rotation of the associated wheel of the vehicle.
  • the brake pads When the disc brake assembly is not actuated, the brake pads are normally spaced apart from the opposite sides of the rotor. Because the brake pads are not positively engaged with the rotor, the brake pads are free to move relative to other brake and vehicle components during vehicle operation. As a result, vehicle induced vibration loads are known to cause undesirable rattle or other noises between the brake pads and the other brake components. To prevent this from occurring, it is known to provide a brake clip between the anchor bracket and the brake pad.
  • the brake clip may have a retraction portion that provides a retraction load that retracts or pulls the brake pad from contact with the rotor when the brake pedal is released.
  • the brake pad wears from a new pad condition to a worn pad condition with repeated use - i.e., engagement with the rotor.
  • the retraction load provided by the retraction clip increases.
  • This invention relates to a disc brake assembly having the features of claim 1, a brake clip having the features of claim 13, and a method having the features of claim 14.
  • a potential advantage of an embodiment of the brake clip is reducing changes in a retraction load of the brake clip.

  • inboard and outboard second brake clips 104A and 104B are similar.
  • the prior art disc brake assembly 100 that is illustrated in FIG. 1 is a well known "Collete" sliding type of disc brake assembly, such as that shown in U.S. Patent No. 5,323,882 to Waterman et al. , U.S. Patent No. Re 30,255 to Rath et al. , and U.S. Patent Publication No. 2013/0192938 to Miller et al. , the disclosures of all of these patents and publication are herein incorporated by reference in entirety.

  • the mounting bolts extend through the first and second threaded openings 123A and 123B, respectively, and are received in threaded openings provided in a stationary vehicle component (not shown), thereby securing the anchor bracket 122 to the stationary vehicle component.
  • other known securing methods can be used to secure the brake caliper 112 to the anchor bracket 122 and/or to secure the anchor bracket 122 to the stationary vehicle component if so desired.

  • the second channels 127 are provided on an inner wall of arm 126 and are parallel to one another.
  • the first and second channels 125 and 127 slidably support the outboard brake pad 132 and the inboard brake pad 134 having the inboard and outboard first brake clips 102A and 102B, respectively, and the inboard and outboard second brake clips 104A and 104B, respectively, assembled therewith.
